Burt Gummer (Michael Gross) and his son Travis Welker (Jamie Kennedy) find themselves up to their ears in Graboids and Ass-Blasters when they head to Canada to investigate a series of deadly giant-worm attacks. Arriving at a remote research facility in the artic tundra, Burt begins to suspect that Graboids are secretly being weaponized, but before he can prove his theory, he is sidelined by Graboid venom. With just 48 hours to live, the only hope is to create an antidote from fresh venom — but to do that, someone will have to figure out how to milk a Graboid!

Gimly

I will always give a _Tremors_ movie a chance, but these last two movies have been very disappointing, and _Cold Day in Hell_ made me feel especially let down. Could not deliver on even its own incredibly weak promise of "Graboids but there's snow now".
_Final rating:★½: - Boring/disappointing. Avoid where possible._
